Referenzdesign von: Texas Instruments
PMP10351, 85-265VAC input, 12V/1.5A PSR Flyback Reference Design. This reference design uses the UCC28713 primary-side regulated (PSR) flyback controller to generate a 12V/1.5A output from a universal AC input. The valley switching of the UCC28713 allows this low-cost design to achieve an average efficiency over 87%, no load losses are less than 50mW. The PSR function eliminates the need for an optocoupler and TL431, greatly simplifying the circuit and reducing cost
